MongoDB Foreign Data Wrapper 5.4.0 release notes v5
Released: 26 May 2022
Enhancements, bug fixes, and other changes in MongoDB Foreign Data Wrapper 5.4.0 include:
| Type | Description |
|---|---|

| Bug Fix | Force type modifiers for NUMERIC type. |
| Bug Fix | Fix data type incompatibility between NUMERIC types. |
